An alpha particle (a helium nucleus, containing 2 protons and 2 neutrons) starts out with kinetic energy of 10.3 MeV (10.3 times 10^6 EV), and heads in the +x direction straight toward a gold nucleus (containing 79 protons and 118 neutrons). The particles are initially far apart, and the gold nucleus is initially at rest. Answer the following questions about the collision. What is the initial momentum...

An alpha particle with a kinetic energy of 12.0 MeV makes a head-on collision with a gold nucleus at rest. What is the distance of closest approach of the two particles? (Assume that the gold nucleus remains stationary and that it may be treated as a point charge. A gold nucleus has 79 protons, and an alpha particle is a helium nucleus consisting of two protons and two neutrons. The mass of an alpha particle is 6.64424 x 10-27 kg....

An alpha particle consists of two protons and two neutrons together in one nucleus with a mass of 6.64×10−27 kg and charge +2e. The alpha particle flies at 3.0×106 m/s from a large distance toward the nucleus of a stationary gold atom (charge +79e). e=1.6×10−19C,k=9.0×109Nm2/C2. Determine the distance of the alpha particle from the gold nucleus when it stops.

A nucleus whose mass is 3.730032 x 10-25 kg undergoes spontaneous "alpha" decay. The original nucleus disappears and there appear two new particles: a He-4 nucleus of mass 6.640678x10-27 kg (an "alpha particle" consisting of two protons and two neutrons) and a new nucleus of mass 3.663533 x 10-25 kg (note that the new nucleus has less mass than the original nucleus, and it has two fewer protons and two fewer neutrons). In these calculations, it is very important to...

protons and two neutrons, and has a mass of 6.64×10−27kg. A
horizontal beam of alpha particles is injected with a speed of
1.3×105m/s into a region with a vertical magnetic field of
magnitude 0.180 T . A) How long does it take for an alpha particle
to move halfway through a complete circle? B) If the speed of the
alpha particle is doubled, does the time found in...

Please show all equations and work An alpha particle (nucleus of a helium atom) has a speed of 3x10^6 m/s and moves in a circle of radius 10 cm in the x/y-plane due to a uniform magnetic field. (a) What is the magnitude and direction of the magnetic field? (b) What is the cyclotron frequency of the alpha particle? (c) Through what potential difference was it accelerated? (d) What is its energy in units of electron-volts?

An alpha particle with a kinetic energy of 10.0 MeV makes a head-on collision with a gold nucleus at rest. What is the distance of closest approach of the two particles? (Assume that the gold nucleus remains stationary and that it may be treated as a point change. The atomic number of gold is 79, and the alpha particle is a helium nucleus consisting of 2 protons and 2 neutrons).
